Data quality and method

What is a Rodden Rating in celebrity astrology data?

A Rodden Rating labels the reported provenance of public birth data so readers can distinguish documented times from biographies, quotes, conflicting reports, and speculation.Reviewed · 2026-08-24 · Educational astrology content
Direct answer

The Rodden Rating system, used by Astro-Databank, classifies the quality and source type of celebrity birth data. It does not rate whether astrology is accurate; it rates how the birth time was reported and documented.

Key points

  • AA and A indicate stronger source paths than B, C, or DD.
  • A precise clock time can still have weak provenance.
  • Conflicting sources should remain visible.
  • Unknown time means angles and houses should not be treated as reliable.

Method

  1. Read the rating and source note together.
  2. Open the cited record where possible.
  3. Limit interpretation to what the data quality supports.

Limits and responsible use

  • A rating is a provenance label, not a guarantee that a record is error-free.
  • Do not upgrade a rating without a stronger source.
